| To EFC. X7655B BY/RD2/ML31.12.27. SEQUENCE STARTER MOTOR - 2.B.1 SCHEME. With reference to your suggestion that the motor for 9-EX be fitted to the rig in your laboratory for test, I would point out that the motor as built for 9-EX will not fit on the rig as that is similar to 14-EX (E.A.C.7), it is therefore not possible to test this on your rig.
